Land Development/Reuse Remediation

Land Development/Reuse Remediation

GeoDesign completed Phase I, II, and III environmental site assessments including hazardous lead and asbestos surveys at various locations throughout a redevelopment area. Field investigations included the use of ground penetrating radar and electromagnetic surveys, soil vapor surveys, soil sampling by various methods and groundwater monitoring well installations and sampling. GeoDesign prepared a Remedial Action Plan for soil and groundwater remediation and developed a soil management plan, bid documents and technical drawings and specifications for a 56,500 cubic yard excavation. We designed and inspected installation of 200 foot long cantilever solder pile and lagging retaining wall, which was installed in contaminated soil. We supervised and directed resident field engineers performing quality assurance inspections and testing which included stockpile testing, soil confirmation sampling, compaction testing and sieve analyses.
